A further object is to produce an ignition strip Vhaving all theingredients necessary vfor the ignition intimately adhered thereto sothat portions Y of the strip may be cut to form ignition discs.

Other objects and advantages Will be apparent during the course f thefollowing description.

In the accompanying drawings forming a part of this specification and inwhich like numbers are employed to designate like parts throughout thesame,

Fig. l is a plan View, showing the blank and the manner in'which theignition strips are formed thereon;

Fig. 2 is a crossr sectional view taken on the lin 2 2 of Fig. 1;

Fig. 3 is a cross sectional View of a cigarette having one of myignition discs positioned in the end thereof;

Fig. 4 is a cross sectional View on an enlarged scale of a modiiied formof my strip; and

Fig. 5 isa view similar to Fig. 3, showing one of the modified discs inthe end of the cigarette.

It is customary to light the ordinary cigarette by subjecting the sameto the heat of a match, flame lighter, or heated wire. Therefore, it isnecessary to have one of these igniting means handy or the cigarettecannot be ignited.

Applicant has therefore devised an igniter which maybe applied to theend of a cigarette so that the same may be ignited by merely Abodimentof my invention, the numeral 5` designates a blank ofY thincigarette-like paper,` upon which I place a series of spots of adhesiveand explosive material as shown at 6.

As` soon as the explosive material has been l properly adhered to theblank, I deposit thereon,

rette as shown in Fig. 3 and secured thereto in any suitable manner, asby adhesive or by crimping the ends of the cigarette over or around thedisc.

In the modified form shown in Figs. 4 and 5, the only difference is thatI have added a second sheet of thin paper 9 which will underlie theexplosive material 8.

In the modified form the discs are cut in the same manner as shown inFig. 5.

The result of this construction is that when Y Y tobacco. Y

scratching the end of the cigarette against an' l,

abrasive surface capable of causing the igniting material to burst intoflame and is somewhat similar to the igniting cap described inapplicants Patent No. 2,422,277 of June 17, 1947, the difference being,however, that applicant has improved his igniting strip by adding to theunderface thereof a second spot of explosive material, which tends tofurther drive the ame deeper into the tobacco so that a more positiveignition is guaranteed. i. y

In the accompanying drawings wherein for the purposeof illustration isshown a preferred em- However, it must be here understood that the smallamount of explosive is not suiiicient to cause any appreciabledetonation which would tend to frighten the user.

In the modified form shown in Figs. 4 and 5 the action is the samewiththe exception that VAthe second set of paper delays the flame reachingthe tobacco slightly so that it concentrates and increases the heatgenerated by the explosion,

' which may be useful With certain kinds of tobacco l which arehard toignite.

resorted to Without departing from the spirit of the invention or thescope of the subjoined claim.

Having thus described my invention, I claim:

A cigarette having an igniter at one end thereof, said ignitercomprising a blank disc having an explosive material centrally disposedthereon and on both sides thereof, the explosive material area on theouter end of the cigarette having an overlying protective coating ofgnitng material, said disc and said material overlying the tobacco atthat end'of the cigarette and having the margins of said disc adhered tothe inner end margins of the cigarette Wrapper, whereby the ignitingmaterial will be exposed for contact-With an igniting abrasive, theexplosive on the interior side of the disc being effective when ignited,to direct ames inwardly toward the tobacco of the cigarette.
